A Quick Lesson in Boolean

I often see scripts that are checking for True/False values using an If/Else statement like the one below.

if($value){
    'True'
} else { 
    'False'
}

While this technically will work for Boolean values, there are situations where this will not work. For example, if you pass the string value of “False” to the statement above it will evaluate as True. This is because the if condition in that code is not checking for True, it is checking for if exists. In that statement anything that is not Boolean False, Null, an empty string, or 0 will return True. However, if you specify a value must be true or false, PowerShell will auto-convert things like the string equal to ‘False’ as actually being false.

This is why I always recommend using the full condition of if($value -eq $true). Not only will this give you the ability to account for variables you may not be able to control, it also gives you a way to handle non-Boolean values. You can test it out for yourself using the snippet below, and see how the different ways of writing this If/Else statement work out.

Function Test-Boolean($value, $test){
    if($value -eq $true){
        $Result='True'
    } elseif ($value -eq $false) { 
        $Result='False'
    } else {
         $Result='Else'
    }

    if($value){
        $IfElse = 'True'
    } else { 
        $IfElse = 'False'
    }

    [pscustomobject]@{TrueFalse=$Result;IfElse=$IfElse;Value=$value;Test=$test}
}


Test-Boolean $true 'True boolean'
Test-Boolean 'true' 'True string'
Test-Boolean 1 '1 integer'
Test-Boolean $false 'False boolean'
Test-Boolean 'false' 'False string'
Test-Boolean 0 '0 integer'
Test-Boolean 'random' 'Any other string'
Test-Boolean 2 'Any other integer'
Test-Boolean ([string]::Empty) 'Empty string'
Test-Boolean ' ' 'Blank string'
Test-Boolean $null 'Null value'

After you run the snippet you should see results like the one below showing you how the two different If/Else statements evaluated the different values.

Display Profile Functions

If you are like me and have multiple machines you work on with different profiles, it can be difficult to remember which profile contains which functions. So, I wrote a quick function that will display all the functions for me on start up.

Just add the code below to the bottom of your $profile file.

Function Get-ProfileFunctions {
    $__ProfileFunctions = Get-Content $profile | Where-Object { $_.Trim() -match '^function' } | Foreach-Object {
        $_.Replace('{', ' ').Replace('(', ' ').Split()[1]
    }

    if ($__ProfileFunctions) {
        Write-Host "Profile functions loaded`n$('-' * 24)" -ForegroundColor Yellow
        $__ProfileFunctions | ForEach-Object { Write-Host " - $($_)" -ForegroundColor Yellow }
        Write-Host "`n"
    }
}
Get-ProfileFunctions

Now when you open PowerShell you will see a prompt like the one below showing you the functions you have in the profile file.

Profile functions loaded
------------------------
- MyCustom-Function1
- Get-ProfileFunctions

You can also run Get-ProfileFunctions at any time to show the functions again.

Homework – Double Digit Addition without Carrying
My son decided to pretend to be sick from school the other day, so after we finished all the work the teach gave us, I decided to make him some extra work. This code will generate a page with 25 double digit addition problems. They haven’t learn to carry over digits yet, so all sums are less than 10. Maybe someone else out there could get some benefits from it. 
[System.Collections.Generic.List[PSObject]] $page = @()
$j = 0
$blank52 = "<td height=""52""> </td>`n" * 9
$blank20 = "<td height=""20""><br></td>`n" * 9
while($j -lt 5){
    [System.Collections.Generic.List[PSObject]] $rowA = @()
    [System.Collections.Generic.List[PSObject]] $rowB = @()
    $i=0
    while($i -lt 5){
        $a = Get-Random -Minimum 1 -Maximum 10
        $b = Get-Random -Minimum 0 -Maximum (9-$a+1)

        $c = Get-Random -Minimum 1 -Maximum 10
        $d = Get-Random -Minimum 0 -Maximum (9-$c+1)

        if(($b + $d) -gt 0){
            if($b -eq 0){$b=' '}
            $rowA.Add("<td class=""xl66"" height=""52"" width=""115"">$a$c</td>`n")
            $rowB.Add("<td class=""xl65"" height=""52"" width=""115"">+ $b$d</td>`n")
            $i++
        }
    }

    $tableRows = New-Object System.Text.StringBuilder
    $tableRows.Append('<tr height="52">') | Out-Null
    $tableRows.Append($rowA -join('<td class="xl66" width="15"><br>')) | Out-Null

Out-GridView for VS Code

Out-GridView is a great tool for quickly creating selection dialogs or displaying information that you sort. However, when using it in Visual Studio Code (VS Code), it tends to display the grid window behind the VS Code window. So, in an effort to prevent me from having to click my mouse one more time, I created the function Out-GridViewCode. This function uses all the parameters as the standard Out-GridView, just add some extra functionality to ensure the grid window is the active one. When using the Out-GridView it will automatically bring the grid windows to the front. If you use the -PassThru or -Wait parameters Out-GridView does not release control until the windows is closed. So, in this situation the function will minimize the VS Code window allowing the grid window to be displayed. Then once the grid window is closed, VS Code will restore itself.

Note: This is designed for use with PowerShell 5 and below. It does not provide a replacement for the lack of Out-GridView in PowerShell Core 6.0. That fix is coming in PowerShell 7.0.


Function Out-GridViewCode{
<#    
.SYNOPSIS
    Sends output to an interactive table in a separate window. With extended support to display Out-GridView as main window when using VS Code
    
.DESCRIPTION
    The Out-GridView cmdlet sends the output from a command to a grid view window where the output is displayed in an interactive table. However, when you use VS Code the window appears in the background. Running this wrapper will bring the window to the front. 
	
	Parameters remain the same as the orginal Out-GridView
    
.PARAMETER InputObject
        Accepts input for Out-GridView.
            
.PARAMETER Title 
        Specifies the text that appears in the title bar of the Out-GridView window.
        
.PARAMETER OutputMode 
        Send items from the interactive window down the pipeline as input to other commands. By default, this cmdlet does not generate any output. To send items from the interactive window down the pipeline, click to select the items and then click OK.
		
.PARAMETER PassThru
        Indicates that the cmdlet sends items from the interactive window down the pipeline as input to other commands. By default, this cmdlet does not generate any output. This parameter is equivalent to using the Multiple value of the OutputMode parameter.
        
.PARAMETER Wait
        Indicates that the cmdlet suppresses the command prompt and prevents Windows PowerShell from closing until the Out-GridView window is closed. By default, the command prompt returns when the Out-GridView window opens.

Remove First Entry in Fixed Array

Here is a quick little trick for removing the first entry in a fixed size array. This can be used when you receive the error message: Exception calling “RemoveAt” with “1” argument(s): “Collection was of a fixed size.”

# Remove first entry
$array = $array[1..($array.Length-1)]


Example

PS C:\> $array = 1..5
>> Write-Host 'Initial Value'
>> $array
>> $array = $array[1..($array.Length-1)]
>> Write-Host 'After Value'
>> $array

Initial Value
1
2
3
4
5
After Value
2
3
4
5

Switch Statement 
switch ($value)
{
    1 {"It is one."}
    2 {"It is two."}
    3 {"It is three."}
    4 {"It is four."}
}

Details

To check multiple conditions, use a Switch statement. The Switch statement is equivalent to a series of If statements, but it is simpler. The Switch statement lists each condition and an optional action. If a condition obtains, the action is performed.


Example

PS C:\> $value = 3
>> switch ($value)
>> {
>>     1 {"It is one."}
>>     2 {"It is two."}
>>     3 {"It is three."}
>>     4 {"It is four."}
>> }

It is three.
